Drainage is key to sustainable site development, warns new team member

Syntegra is delighted to unveil a new member of its team as it expands its services and brings all its hydrology and flood risk assessment roles inhouse for the first time.

Arwyn Norris is our new Director of Civils and Infrastructure and brings with him a wealth of experience in the field which we will seek to capitalise on as we grow this side of our business.

As new mandatory rules are set to be implemented from January regarding SUDS standards – Sustainable Urban Drainage Systems – his hydrology expertise and knowledge will be invaluable as we seek to increase our service provision in this area of work helping developers introduce drainage systems that are as environmentally friendly as possible and replicate something as natural as possible.

Arwyn has been working for us on a freelance basis for the past two years while we outsourced this line of work so knows our company ethos and will bring invaluable assistance to our team, said Syntegra Managing Director Alan King.

Arwyn will be writing flood risk assessments and helping draw up detailed drainage designs for a mixture of sites from residential to commercial, hotel and regeneration developments. His initial work co-ordinating our hydrology services will also include a few highways schemes – access designs and road schemes.

‘I’ve been involved in the industry for a long time so have a good knowledge of what larger schemes need compared with single householder plans,’ he said. ‘Schemes are never the same so we operate on a bespoke basis although adhering to the same principles.

‘We look to work with developers at the earliest opportunity when they’re looking at a site so we can look for opportunities for the SUDS scheme.

‘We often see schemes drawn up by architects with no thought about where they’re going to put the scheme and it becomes a battle where they have to squeeze everything to make space for it and they lose value because they’re not getting as much on the site as they expected.

‘If you get us on board early, we can get a better, more sustainable drainage scheme that everyone can live with, not just an afterthought as has been the case before.

‘It’s actually a key thing that can make or break a site.’

Alan said: ‘Arwyn has an impressive track record in this line of work and we’re delighted he’s agreed to join our team. His knowledge will be a huge asset to clients seeking to do the right and best thing on their sites to mitigate the effects of flooding which are likely to get worse as the full impact of climate change becomes apparent over the coming years.’

‘It made good business sense to bring Arwyn in house to join our team on a permanent basis. We can all expect to learn from him about hydrology and other services and we can now be confident we are offering all our clients the best available advice in this critical area of sustainable development.’

* In 2015, world leaders agreed to 17 goals for a better world by 2030. These goals have the power to end poverty, fight inequality and stop climate change. Guided by the goals, it is now up to all of us, governments, businesses, civil society and the general public to work together to build a better future for everyone.

Syntegra’s work is underpinned by many of the goals.


Goal 11 – Sustainable Cities and Communities: Make cities and human settlements inclusive, safe, resilient and sustainable.
The world’s population is constantly increasing. To accommodate everyone, we need to build modern, sustainable cities. For all of us to survive and prosper, we need new, intelligent urban planning that creates safe, affordable and resilient cities with green and culturally inspiring living conditions.


Target 11.5- Reduce the adverse effects of natural disasters
By 2030, significantly reduce the number of deaths and the number of people affected and substantially decrease the direct economic losses relative to global gross domestic product caused by disasters, including water-related disasters, with a focus on protecting the poor and people in vulnerable situations.
